T0 all whom t may concern:

Be it known thatl, JOHN EARNEST LOWE,

a citizen of the United States, and a resident of Good Hope, in the county of McDonough and State of Illinois, have invented a new and useful Measuring-Pump, of which the following is a specification.

The invention relates to measuring pumps,

and the objects thereoll are to generally iniprove the construction and increasethe utility, accuracy andeiliciency of devicesof this character. 1f

The invention accordingly consists in various improvements in pumps of this classor character, directed more particularly to .the

pump-head; to the gallon measure adjusting devices; to the fractional measuring means; to the. means for assemblingoand disassem-l bling, whereby these operations may be speedily done; and to carrying out of minor' objects, some of which will be obvious and Some specifically pointed out. '1v In the accompanying drawings, which illustrate my invention, Figure 1 isa side elevation, the inlet, ltering, and discharg-y ing means not shown; Fig. 2, avertical', central, transverse section in the line 2 2 in Fig. 1, and showing also the elements above noted as not shown in said figure; Fig. 3, an enlarged detail, partly in section and partly in elevation; Fig. 4, a detail, a side elevation; Fig. 5, a top plan detail of the head and some of the elements engaged therewith; and Fig. 6, a ragmental detail, showing the gallon-fraction-measuring means shown Fi 8, but seen from the opposite side.

onsidering said drawings in detail and referring to each element and part .thereof` (where required) by a distinguishing numeral, uniformly employed, 2 vindicatesfa base having an aperture 3 for the reception v 10 is a cylinder, the upper and lower 'por f' tions of which are providedv respectively 2- with tapered terminals 11, 12, the latter resting on'the seat 8.

minal 11 of the cylnder. The head 1- lits had.

snugly on the uPper'e\nd of the cylinder l0 and the lower end ofthe .latter fits snugly into the seat 8 in the base. a l I A'rame, of whiclfi 22 indicates the base plate, is provided with an .aperture for the engagement of astuiing box 19 whichy has the usual axial bore for the passage .of the rodlB. l

2O designates each one of a plurality of rods, threaded at` both ends.

lower end. i' The cylinder is held securely in place by drawing these nuts down firmly on the threads of manner.'. v

Integral with the lbase-plate 22v are standards 25 and 26, united at their upper ends by a head 27, Fig.,6. `28'isa rib'on the outer prisescheeks 29 having registering slots 30 providing each a bearingl 31, provided in part by aboss 31a. It is .provided also with a vertically arranged aperture 32, Fig. 5,

These rods pass each through aperturesin the plate 22 and -fiange 9. A. nut 23l engages the upper' l end of each rod 20, and a nut 24 engages its vtle ,rodsyand'in an evident -face of the standard 26. Thehead 27...corn 1.

stops 51 and 52 are arranged on the respective faces of the rack bar. Register 531s secured upon-the cap 40 and adapted to be actuated by a wrist-pin 54, on the journal 37, as shown in Figs, 2 and 4.

55 1s a counter having a tripping lever 56, and said lever is actuated by a' trip 57.

tired to the rack bar, when said -raclr bar has reached its limit of movement.

5 3 is a register, suitably secured on the cap 40 and actuated by a wrist pin 54 carried by the journal 37.

55 is a counter having a trippinglever 56 adapted for registration by a trip 57 fixed to the rack bar.

58 is a bolt slidable and rotatable in a recess in the standard 26 and an opening through the standard 25, and is provided with a handle 59 by which it may be opg erated and also vby which its extent of movement is limited. The stop 52 at the limit of upward movement of the rack bar enf fractional parts of `a gallon or other specific predetermined measurement is delivered at a single stroke of the piston.l

75 is the usual faucet, communicating with the discharge pipe 68 by means of any suitable connections 76, 77, 78.

Assume the parts to be in the relative positions shown in Figs. l and 2. Rotation of the crank 39 will impart like movement to the journal 37 and thereby to thepinion 38 and thereby raise the rack bar 33, which isA in' mesh therewith. The piston rod will be drawn therewith and the head 14 thereof will act on the valve 6 to draw a charge of oil from the source of supply connected with the inlet pipe 4 inan evident and ordinary manner. During this movement .the trip 57 will contact the trigger 56 and actuate the counter 55, and simultaneously or approximately so the wrist 54 will actuate the register 53. The gage-boss 52 will strikev and its extent of movement stopped by the f adjustment or gage-screw 48 which engages standard and into position to be struck by,

the gage-boss 51 on fthe rack bar 33. These gage-bolts are preferably placed to measure one, two, or three quarts, as shown in Fig. 1.`

lt is frequently necessary to examine the par 71s within the cylinder 10, and it is theretore desirable that its interior be easily and quickly accessible. Removal of either-set of nuts 23 or 24 from the rods 20 permits of the plate 22 and all parts engaged there-v i with being lifted off the head 17, and said.

head may then be instantly removed from od' the cylinder 10. It is desirable also that ready access may be had to the lilter elements. RemovalA of either set of nuts 91 permits the tube 60 to be Jreed, and it may instantly be removed. The cap 40 may be removed from the head 27 by removal of the two screws 46 and 47 and the cap 50.

The head 4beingcast integral with the standards, and. they being integral with the plate 22, provides a simple pump top which cannot be twisted or, so assembled as to cause binding or strain on any'o the parts. The brace-rod 49 lends additional strength.

Having thus described my invention, l claim as new.:

A measuring pump including a cylinder,

a piston therein, a pistonl rod connected to the piston, a frame removably secured to the cylinder, a hollow head carried by the frame, a rack bar connected to ,the piston rod and operable through the frame, a solid partition/,disposed .within the head, and a screw stop adjustably mounted in said partition and arranged in the path of movement of saidl stop, said screw stop being `wholly secured within the head.

In witness whereof, I hereto atliX my signature this eleventh day of November, 1913.
